Whether you are planning to file a patent or are in the process of filing one, you might be wondering how long a non-provisional patent lasts. A non-provisional patent application is a much more complicated process than a provisional patent. A provisional patent is only good for a year, giving the inventor enough time to file a non-provisional patent application. Once that year is up, the provisional patent will expire. Non-provisional patent applications last 20 years.

Non-provisional patents have a 20-year lifespan

Non-provisional patents are valid for a minimum of 20 years and may last longer. Patents issued after June 1995 are subject to a 20-year lifespan. Patents may be extended for additional five-year terms if the patent has a terminal disclaimer. A terminal disclaimer is a requirement for utility patents when claims overlap in a different patent. This disclaimer is a tie between the patients’ lifespans.

The lifespan of a non-provisional patent is generally twenty years from the date of filing. This period does not include any provisional patent applications that were filed before the patent was granted. Provisional patent applications are temporary in nature and do not count towards the 20-year limit. Nevertheless, they can be extended for an additional year if the inventor wishes. Non-provisional patents have a 20-year lifespan and are usually issued by the Patent Office within a year of filing.

Provisional patents are limited in number. If there is more than one provisional patent application, the patent may be longer than 20 years. The term of a patent does not start until the date of issuance, but from the date, the application is filed. Hence, provisional patents are more commonly used by startups than by big pharma companies. This is because of their shorter lifespan and higher cost.

Unlike provisional patents, which only last ten years, design patents have a 20-year lifespan. They may be extended, however, by a few months. The United States Patent Office awards some design patents a patent term adjustment. The adjustment is typically noted on the front page of the patent. If the patent is awarded a term adjustment, it will state that it has been extended under 35 U.S.C. 154(b).

If you are unable to pay the maintenance fees after the initial grant, the patent may become invalidated. If you can pay the maintenance fees, you might be able to bring your patent back. This is an ideal situation if your product is already widely used. It can also increase your revenue if it is more expensive than the patent was worth. If you are planning to sell your product, you might want to extend the patient’s life.

Once you have filed your application, the USPTO will review your application. Once approved, your non-provisional patent will provide you with 20 years of protection from the date of your initial application. Provisional patents are fast and easy to file but have a comparatively short lifespan. The USPTO generally takes one to three years to make a decision. Therefore, a provisional patent application may be a good idea if you have an idea that has potential.

They require more work

Non-provisional patents are typically referred to as utility or patents and are considered the standard method of protecting an idea. In many ways, they function as a bridge between the concept stage and a patent, but there are differences between provisional and non-provisional patents. A provisional patent application is not seen by the patent office and establishes an early filing date that gives your idea priority over others.

Although a provisional patent has limited protection, it can get you the protection you need to move quickly into production or distribution, seek investment capital, or start marketing your idea. However, provisional patents take between 22 months and a year to issue, making them unsuitable for small inventors. This time will be wasted if you decide to proceed with a non-provisional patent application. To make your time well spent, use the gap between provisional and non-provisional patents.

While a provisional patent may be appropriate for short-term, non-provisional patent applications require more work. They can also be more expensive than non-provisional patents. Typically, provisional patent applications are chosen by inventors who want to patent an idea quickly but do not want to spend a year waiting for it to be thoroughly reviewed. Provisional patent applications are a good option for one-year patent protection, but if you need the patent sooner, it may be worth considering a non-provisional patent.

Why file a non-provisional patent

What are the advantages of non-provisional patents? First of all, they are not subject to the year-long waiting period. That means, if you decide to file for a non-provisional patent, your old provisional patent will become a non-provisional patent. This means that, when the year has passed, the patent office will see your non-provisional before your competitor. The second benefit is that you have the option to make your invention public while you’re waiting for your non-provisional patent application to be processed.

Non-provisional patents also have the advantage of being longer than provisional ones. In the United States, a non-provisional patent will have a 20-year term, and if you filed it before May 13, 2015, the term will be fourteen years. However, it is important to note that if you file a non-provisional patent within a year of the date of your provisional patent, you will be able to claim priority for your second application.

The main advantage of filing a non-provisional patent is its price. In contrast to a non-provisional patent, a provisional patent is cheaper and allows you more time to perfect your invention. However, it expires after a year, so it is important to be aware of the expiration date of a provisional patent. Once the patent expires, you must file a non-provisional patent application to protect your new invention.

If you want to protect your invention in the long term, it is essential to file a non-provisional patent application before you release your invention to the public. A provisional patent expires after one year, so filing a non-provisional patent is crucial if you want to protect it for the next several years. There are many other advantages to non-provisional patents as well. You can also avoid paying the initial fee for your non-provisional patent application.

Choosing a patent is a big decision. In some cases, patents have multiple terms, so you need to consider all of them. However, remember that your patent will have different terms depending on how you choose to file it. If you file it early enough, you may have a much longer term than you think. There are several ways to determine if your patent will expire in that time.

If your provisional patent application is rejected, you may want to refile a non-provisional patent application. The filing date of the new patent application must be at least a year before the first provisional patent expires. If your non-provisional patent application is rejected, the examiner may be able to use prior art that predates your new filing date. You cannot “back date” your non-provisional patent application, however.

Applying for a non-provisional patent

Some inventors file the official nonprovisional application immediately to receive full patent protection over the entire period of 20 years.

This will ensure that you don’t waste time filing the provisional applications. You will need to be more careful with your invention. A provisional application is your best option if you fear that someone may steal your intellectual property.

A provisional application can be problematic because it expires twelve months after you file it. This could make it difficult to file your non-provisional applications on time. This route will require you to save enough money to be able to apply for the actual patent within a year. You will need to be motivated because the provisional patent application basically forces you to do something.

You will also find different rules for continuing applications, international applications, and foreign priority. These might not be applicable to your patent but it is important to thoroughly research the patent process in order to determine which category your invention falls under. A patent attorney can help if you aren’t sure about something.

Mistakes to avoid when applying for a non-provisional patent

1) Rely on a low-quality provisional application as the basis. Although you could file a provisional application for patent protection yourself, you want the patent application to be high in quality. If you file a provisional patent application with insufficient details on the operation of the invention, it is important that you immediately follow up with a high-quality application. You may have good reasons to file a rough provisional patent application. This could be because there are other people working in the same field as you and you want your competitors to win. It also might be a good idea to do this if your invention is going to be made public. If this happens, you should quickly go back and complete the invention with a follow-up provisional. Provisional patent applications do not have to meet any formal requirements. You can scan a drawing on a napkin or a slide deck of PowerPoint slides or even a set of notes. However, if the patent is ever questioned, patent examiners are likely to be happier and more reluctant to grant the eventual non-provisional application.  If you don’t have the time or the desire to learn all the rules and are not proficient in writing, it is best to hire a patent attorney

2) Do-it-yourself patent filing. It is not a law that an inventor should use an attorney who has a good understanding of the business to file a patent application. Although you could theoretically do it yourself, we have seen numerous cases where inventions were destroyed by DIY patent applications that caused serious problems and prevented the inventor from getting a patent. A DIY patent applicant is unlikely to get a patent. If they do, it’s likely that valuable assets will be lost. For any communication with the Patent Office, you should hire a competent patent attorney.

3) The invention may be used or sold in public before a patent application is filed.  In some countries, public disclosures prior to filing a patent are automatically disqualifying. Although the US and Europe allow you to file a patent within a year of a public disclosure, it is still a bad idea for any public disclosure prior to filing. If there isn’t a patent application in place before your public disclosure or sale, such public disclosure may invalidate the patent.

4) Don’t disclose known prior art to the patent office.  Such failure can also invalidate the patent as failing your duty of disclosure to the patent office.  You can use an Information Disclosure Statement (IDS) form to supply prior art information in your patent application

5) Failing to pay patent maintenance fees. After your utility patent has been issued, you’ll need to pay annual maintenance fees for four, eight, and twelve years. The patent will expire if you fail to pay the fees.  The United States Patent and Trademark Office is responsible for examining patent applications and determining whether or not a patent should be granted. If a patent is granted, you have to enforce your rights. If you haven’t paid maintenance fees, then your patent may expire. You should also consider filing an appeal. You will need to pay the filing fee and spend some attorney time.  In sum, a non-provisional utility Patent lasts for 20 years. To maintain your patent, you must pay maintenance fees for the remaining 20 years.

Can I Get a New Patent During My Non-Provisional Patent’s Lifetime?

We can learn from the pharmaceutical industry on how to extend patent life, where each additional year can be worth billions.  Patent protection can be extended for commercially successful drugs by obtaining additional patents that cover new formulations of known compounds that are clinically superior to the existing drug formulation. Patenting new formulations that encourage patient compliance, such as those that require less dosing, are easier to use, have better therapeutic outcomes, have side-effect profiles, or protect market share, is a great way to defend against generics. New formulations can be approved by the FDA faster if they are sufficiently similar to the original drug.

Sustained-release formulations are examples. After Lilly’s patent for Prozac expired, the company created and received FDA approval and patent protection for a Fluoxetine formula that is a once-weekly sustained-release. Bristol-Myers Squibb was also granted FDA approval and patent protection for its extended-release formula of Metformin hydrochloride, a diabetes drug. This new formulation, known as Glucophage XR for type II diabetics, is now available under the brand name. 

Patent protection is also available for new formulations that allow for new routes for the administration of known drugs. GlaxoSmithKline’s annual sales of Imitrex (Sumatriptan), a migraine treatment drug, is more than $ 1 billion. In 2006, the patent covering the original compound will expire. To extend patent protection and preserve market share, GSK has obtained FDA approval. 


Chiral drugs account for two-thirds of all drugs currently on the market. This means that while one form is effective, the other can be dangerous or ineffective.  A second issue has emerged regarding enantiomeric drugs (drugs that are made up of two mirror-image molecules with the same chemical composition), derived from racemate pharmaceuticals, for which a company holds a patent.  Drugs are often composed of different stereoisomers. These mixtures can be either enantiomers or isomers. A racemate or ‘racemic combination’ is a compound that contains an equal number of enantiomers. A lot of companies that hold a patent for a racemic drug are tempted to remarket it as one enantiomer under another patent. This is called “racemic switching” and allows drug companies to submit an FDA application for approval of an enantiomer before the expiration of the racemic drug patent.

Before applying for extension patent applications, you need to make sure that you have an invention worthy of a patent. You should also make sure that the invention is new. If you have been working on your invention for years and have not made a written record, then you probably do not have any patent rights. However, you may have some trade secret rights. You need to keep the trade secret so that others can’t steal it.

Next, you need to determine the best way to go about getting a new patent. You can either do it on your own or you can hire an attorney. You can get a patent attorney to file a non-provisional application on your behalf. You will be able to use this to fill in any voids in the subject matter that are disclosed in the provisional application.

In sum, a non-provisional utility Patent lasts for 20 years. This period starts at the original filing date and not when the patent was granted. Patent applications can take as long as three years to process. To maintain your patent, you must pay maintenance fees for the remaining 20 years.
